3ede53f3e1 Clean up the error handling in the
write path.  In particular, this should
solve some problems people have seen with
bsdtar not exiting on various write errors.

527b6597a0 Clean up some consistent confusion between "dev" and "rdev."
Mostly, these were being used correctly even though a lot of
variables and function names were mis-named.

In the process, I found and fixed a couple of latent bugs and
added a guard against adding an archive to itself.

61fac2242c Update file flag handling.
The new fflags support in archive_entry supports Linux and FreeBSD
file flags and is a bit more gracious about unrecognized flag names
than strtofflags(3).  This involves some minor API breakage.

The default tar format ("restricted pax") now enables pax extensions
when archiving files that have flags.  In particular, copying dir
heirarchies with 'bsdtar cf - -C src . | bsdtar xpf - -C dest' now
preserves file flags.  (Note the "p" on extract!)

While I'm here, fill in some additional explanation in the
archive_entry.3 manpage, fill in some missing MLINKS, mark some
overlooked internal functions 'static', and make a few minor style
fixes.

4db0943252 Set the 'dump' flag for shardump format.
Credit Juergen Lock.
Pointy hat to me for deleting this somewhere along the way.

c968be6d98 Yucky bug: Don't emit 'mkdir' commands for regular files in shar archives.
While I'm here, add some logic to avoid "mkdir ."

d911e48507 * Plug a buffer overrun in ACL parsing. (archive_entry.c)
* Re-use a single buffer for shar output formatting rather
   than hammering the heap. (archive_write_set_format_shar.c)
 * Fix a handful of minor memory leaks and clean up some of the
   memory-management code.

aee47dd7c8 More work on ACLs: fix error in archive_entry's ACL parsing code,
try to set ACLs even if fflag restore fails, first cut at reading
  Solaris tar ACLs

Code improvement: merge gnu tar read support into main tar reader;
  this eliminates a lot of duplicate code and generalizes the tar
  reader to handle formats with GNU-like extensions.

Style: Makefile cleanup, eliminate 'dmalloc' references, remove 'tartype'
  from archive_entry (this makes archive_entry more format-agnostic)

Thanks to: David Magda for providing Solaris tar test files

df3c1316b0 Many fixes.
Portability: Thanks to Juergen Lock, libarchive now compiles cleanly
on Linux.  Along the way, I cleaned up a lot of error return codes and
reorganized some code to simplify conditional compilation of certain
sections.

Bug fixes:
  * pax format now actually stores filenames that are 101-154
    characters long.
  * pax format now allows newline characters in extended attributes
    (this fixes a long-standing bug in ACL handling)
  * mtime/atime are now restored for directories
  * directory list is now sorted prior to fix-up to permit
    correct restore of non-writable dir heirarchies

a1f17de172 Minor API tweak: The format-specific write_header function now sets
the size in the archive_entry object to zero if that format doesn't
store a body for that file type.  This allows the client to determine
whether or not it should feed the file body to the archive.  In
particular, cpio stores the file body for hardlinks, tar and shar
don't.  With this change, bsdtar now correctly archives hardlinks in all
supported formats.

While I'm here, make shar output be more aggressive about creating directories.
Before this, commands such as:
    bsdtar -cv -F shar  some/explicit/path/to/a/file
wouldn't create the directory.  Some simple logic to remember the last
directory creation helps reduce unnecessary mkdirs here.

At this point, I think the only flaw in libarchive's cpio support is
the failure to recognize hardlinks when reading.

2710e4d1ef Initial import of libarchive.
What it is:
   A library for reading and writing various streaming archive
   formats, especially tar and cpio.  Being a library, it should
   be easy to incorporate into pkg_* tools, sysinstall, and any
   other place that needs to read or write such archives.

Features:
  * Full automatic detection of both compression and archive format.
  * Extensible internal architecture to make it easy to add new formats.
  * Support for "pax interchange format," a new POSIX-standard tar format
    that eliminates essentially all of the restrictions of historic formats.
  * BSD license

Thanks to: jkh for pushing me to start this work, gordon for
  encouraging me to commit it, bde for answering endless style
  questions, and many others for feedback and encouragement.

Status: Pretty good overall, though there are still a few rough edges and
  the library could always use more testing.  Feedback eagerly solicited.
